FWIW, this is an upstream kernel issue, see:

https://dev-nell.com/rpmb-emmc-errors-under-linux.html
https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1333140
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=759656
https://patchwork.kernel.org/patch/4710641/

it particularly seems to affect the Asus T100. I'm not sure we need a Fedora bug for it, but it's nothing to do with the Fedlet kernel build as it happens.
